Polyurea Coated Cardboard Box

We coated a cardboard box with polyurea and filled it with water immediately afterwords to show how fast it dries. We also tried filling a regular cardboard box with water and it fell apart. The polyurea coated cardboard box also had the ability to keep its shape when filled with a heavy substance, due to the added structural integrity from the polyurea.
